Multiple methods and materials are available for bone defect reconstruction. Bone graft substitute is one of the materials used for reconstruction of bone defect and have been widely used recently. This report describes some cases about complications related to GeneX® which is introduced as mixture of calcium sulfate and β-tricalcium phosphate at manufacturer's official web site. It informed of...

BACKGROUND AND PURPOSE The natural pattern of bone healing in large bony defects following curettage alone as treatment of benign bone tumors around the knee is not well reported. We analyzed the outcome in 146 patients. PATIENTS AND METHODS 146 patients with over 18 months of follow-up who underwent curettage without bone substitute filling or bone grafting for a benign tumor in the distal f...

Bone grafting of the maxillary sinus is attempted to compensate for sinus pneumatization and permit reliable insertion of endosseous dental implants for prosthetic rehabilitation. The aim of the present clinical investigation was to study bone regeneration four months after transcrestal sinus floor elevation via the Gel-Pressure Technique (GPT) and application of pasteous nano-crystalline hydro...

An unmet need remains for a bone graft substitute material that is biocompatible, biodegradable and capable of promoting osteogenesis safely in vivo. The aim of this study was to investigate the use of a novel collagen-hydroxyapatite (CHA) bone graft substitute in the clinical treatment of a mandibular bone cyst in a young horse and to assess its potential to enhance repair of the affected bone...

A prospective study was performed on 34 patients to evaluate the efficacy and safety of a composite bone substitute formed of hydroxyapatite and tricalcium phosphate (Ceraform) with or without gentamycin sulphate (Ceraform-Genta) plus autogenous bone marrow aspirate in the treatment of cavitary bone defects related with benign bone lesions. At the end of the follow-up period, all patients were ...

The aim of this study was to evaluate the clinical performance of a magnesium-enriched hydroxyapatite biomaterial used as bone substitute in a case of mandibular ameloblastoma treated with conservative surgery. A 63 year old male patient was treated for an ameloblastoma in the anterior mandibular profile. After tissue excision, the bone defect was filled with a synthetic hydroxyapatite biomater...
